A beginner course
Thirty lessons that follow one story, with dialogues, exercises, pictures, graded stories and a Speak part in each. In Northern or Southern Vietnamese, whichever you need.
Find the word you mean
Type tomorrow and the candidates come back — ngày mai, mai, hôm sau — each with its meaning and an example, for you to keep the one you mean.

A natural voice for every word
Every word and sentence you keep is spoken aloud, in xAI’s Grok voice or Microsoft’s Hoài My and Nam Minh. Class recordings are transcribed line by line, and a word’s page plays the moment it was said in class.

Echo
Say it back. See which tones came through.
Echo plays a line from your lessons — the class recording itself where you have one, the app’s voice where you don’t — and you say it back. Ask for a check, and a transcriber writes down what it heard; Echo compares that syllable by syllable and names any tone that came through as another. Your pitch is drawn over the voice’s, so you can see the fall you left out.
- Any line of a class recording, and any sentence with audio, can be shadowed
- Tap a syllable to hear the voice, what the transcriber heard, and yourself
- It reports what was heard, never a score — a hint to check with your own ears

Record & Correct
Write it or say it. See what to fix — and why.
Record a voice message for your teacher, or type a paragraph. Once you have confirmed what the transcriber heard, every sentence comes back judged — fine, or corrected and labeled as wording, grammar or a tone heard differently — with one or two plain sentences on why.
- Say what you meant, and a tone the transcriber heard differently is flagged as exactly that — not as your mistake
- A grammar point from your own course book is named when it covers the correction
- Keep any corrected sentence as a study card, or download the recording and send it to your teacher

Get ready for day-to-day conversations
Where are you from? Are you married? Why Vietnamese? Write your answer once with help, hear it said back to each person who asks, and rehearse until it comes out without searching.
Write it, then fix it yourself
Write a few sentences on a prompt from your lesson. The app marks what to fix and gives a hint before the answer, so you find your own mistakes — and keep the fixed sentences as cards.

Read and understand
Reading
Read real Vietnamese. Tap any word you don’t know.
Paste an article or a message — or photograph a menu, a sign, a page. Every sentence gets a translation and can be played, and words that aren’t in your lexicon yet are marked. Tap one for its meaning and its tones, hear the sentence it sits in, and add it with that sentence as its example.
- Words you know stay unmarked — so you see how much you can already read
- Nothing reaches your lexicon unless you add it
- Every sentence you play is kept for you to practice saying aloud

Pronouns
Who is you? It depends on who’s asking.
Vietnamese has no neutral you. People are addressed as family — older brother, aunt, grandchild — and what you call yourself changes with them. The Pronouns page lays the system out in tables, starting from the rule that makes it click: both sides of a conversation use the same pair of words, mirrored.
- Every word and example on the page can be played
- From friends your own age to elders and teachers, each pair of words set out side by side
- A reference, not a quiz — and pronouns stay out of your flashcards if you prefer
PronounsYou & me
The mirror — one hello, both sides
You (younger)
Em chào anh ạ.
em = I (that's you) · anh = you (him)
Him (older)
Anh chào em.
anh = I (that's him) · em = you (you)
-
A man a bit older than you
They are anh · you are em
Em chào anh ạ. Hello!
-
A woman a bit older than you
They are chị · you are em
Chị ơi, cho em hỏi… Excuse me, may I ask…

Picture cards
See the thing. Say the word.
Give a word a picture — generate one, or photograph the real thing — and it gets a card of its own: just the picture, and you say the Vietnamese, with no English to lean on. The picture also shows on the word’s answer side in every review.
- The generator is told to leave out every letter, so the card can’t answer itself
- Nothing is generated until you ask — one tap per word

A picture shows on the answer side while you study, and gives this word a picture → Vietnamese card — you see the image and say the word, with no English to lean on.

Reviews at the right moment
An FSRS schedule brings each card back just before you would forget it — recognition, listening, picture and, for the words you choose, production — and flags the words you keep missing.
Practice before class
Tell it your class days, and what you upload on one is filed under that day’s lesson. Go over everything a lesson covered as often as you like, without disturbing your review schedule.
A nudge, only if you want one
Pick the days and the time, and you get one short email on those days, only if you haven’t studied yet. Pause it for a week whenever you like.
Share your week with your teacher
Send your teacher a private link to what you studied in the last seven days, and turn it off whenever you like.
FAQ
Questions, answered.
What can I upload?
Class slides, PDFs, exercise scans, photos of your notebook, textbook chapters, and audio recordings of your lessons. Vietnamese Buddy reads the text off the page — your handwriting included — and transcribes recordings. A tone mark it can’t make out in your handwriting is flagged for you to check.
Does it work with my course book?
Yes: it reads the page, not a list of known books, so slides, handouts, worksheets and textbook scans all work. Grammar points come from the book you upload, named as the book names them.
One layout gets extra help: books whose chapters have seven numbered sections, from pronunciation to dictation. With a book like that, a recording named after its exercise is linked to its printed page, and the print is used to check the transcript.
I’m not taking a class. Is it still for me?
Yes. Work through the course from the first lesson, get your small-talk answers ready, start with the three starter decks, paste articles into Reading, and write or record a few sentences a day. Anything you find along the way can go straight into your lexicon.
Is there a free version?
Yes. The free plan has the first three lessons of the course, the starter decks, spaced-repetition reviews, the Pronouns guide and the free grammar and word pages. The AI features come with Teaching Assistant and The full package.
Which Vietnamese does it teach?
Your own material is kept exactly as it is written, so whichever your class teaches. The course comes in Northern and Southern editions, and you choose which to follow. The voices are another matter: every voice the app has today speaks with a Northern (Hà Nội) accent. Southern voices are not available yet; your class recordings play your teacher’s own accent.
Do I have to type vocabulary in by hand?
No. The AI pulls words and sentences out of your material; you keep, edit or reject each one in a review queue. To add a single word, type it — in English or in Vietnamese — and a few candidate senses come back to choose from.
How accurate is the AI?
Good, and not perfect — which is why nothing reaches your lexicon until you have confirmed it. It is told to keep tone marks exactly as written and to flag one it can’t make out — and the review queue is where you catch the rest. Treat corrections and translations as a study aid, not a reference work.
Where does the audio come from?
By default from xAI’s Grok voice — the one you hear on this page. In Settings you can switch to one of Microsoft’s two Vietnamese voices. All of them speak with a Northern accent, and one voice reads your whole lexicon, so you learn one accent consistently. And when a word turns up in one of your class recordings, its page plays that moment of the recording — a real speaker, not a synthetic voice.
I read Chinese. Does that help?
A lot. Say so in the setup checklist or in Settings, and Sino-Vietnamese words show the characters they came from, with pinyin, beside the word a Mandarin speaker uses today — spoken by a Mandarin voice. It is told to fill in only cognates it is sure of, and a native Vietnamese word gets none.
Is my material private?
Yes. Each account has its own database, your uploads are never shown to anyone else, and you can export or delete everything from Settings. The Privacy Policy lists every provider that processes your data, and why.
